BACKGROUND OF THE INVENTION

An enterprise content management system provides order to unstructuredinformation. It manages the creation, management, processing, delivery,and archival of any content according to user-defined business rules. Itestablishes relationships between pieces of content, allowing the samecontent to be used in different contexts and renditions. It addsintelligence, creating categorization schema and metadata that makesearch and retrieval faster and more efficient. It automates theprocessing of content through its life cycle. It facilitates publicationof content through multiple channels; for example, the same content canbe published to a Web site, broadcasted as a fax, printed as a textdocument, and sent to a handheld wireless device. It promotesintegration between departments and systems that previously workedwithin silos.

The enterprise content management system includes document repositoriesfor storing documents, content servers for providing access to thedocument repositories, name servers for storing the networkorganization, and clients for providing system access to a user. Securecommunications between the various parts of the enterprise contentmanagement system can be very important. A normal system, which usesnative plain-text communication model, is very vulnerable to dataleakage. There are currently no algorithm or tools or mechanism toenable a user to start using security features that are provided by thesystem immediately, on an as-needed basis.

The invention is described in connectionwith such embodiments, but the invention is not limited to anyembodiment. The scope of the invention is limited only by the claims andthe invention encompasses numerous alternatives, modifications andequivalents. Numerous specific details are set forth in the followingdescription in order to provide a thorough understanding of theinvention. These details are provided for the purpose of example and theinvention may be practiced according to the claims without some or allof these specific details. For the purpose of clarity, technicalmaterial that is known in the technical fields related to the inventionhas not been described in detail so that the invention is notunnecessarily obscured.

Automatic elevation of system security is disclosed. A system forautomatic setting of system security comprises an interface configuredto receive an indication to set a secure mode. The system for automaticsetting of system security additionally comprises a processor configuredto determine that the indication to set the secure mode comprises anindication to set a certificate mode, detect one or more connectedsystems, select one or more certificates, update initialization files,and reinitialize local and connected systems. The system for automaticelevation of system security additionally comprises a memory coupled tothe processor and configured to provide the processor with instructions.

The system for automatic setting of system security automatically setsup certificate-based authentication between a server on an enterprisecontent management system and any other network entities in theenterprise content management system that it communicates with.Reconfiguring the system to use certificate-based authenticationrequires certificate based peer verification. Configuring this manuallycan be very error prone and time consuming. This task begins byautomatically determining all systems in communication with the server.In a large enterprise content management system, even this preliminarystep can be a daunting challenge for a system administrator to performmanually. The server then determines whether an authenticationcertificate is present for each system found to be in communication. Foreach system, if a certificate is not found, one is generated. Thecertificates are packaged into a password protected keystore file anddistributed to each system in communication, as well as to the interfaceAPI on each communicating client. Each system is additionallycommunicated the password file. Changes are made to initialization fileson each system to indicate the path to the certificate package. Tocomplete the process of automatic setting of system security, eachsystem is indicated to reinitialize to reflect the changes made to theinitialization files.

FIG. 1 is a block diagram illustrating an embodiment of a system forautomatic elevation of system security. In the example shown, FIG. 1comprises network 100. In various embodiments, network 100 comprises oneor more of the following: a local area network, a wide area network, awired network, a wireless network, the Internet, an intranet, a storagearea network, or any other appropriate communication network. In theexample shown, user system 102 comprises a user system (e.g., acomputing system for operation by a user). In various embodiments, thereare 1, 6, 22, 122, 1059, or any other appropriate number of user systemscommunicating with network 100. In some embodiments, user system 102comprises a system accessed by a user directly (e.g., the user is inproximity with user system 102). In some embodiments, user system 102comprises a system accessed by a user remotely (e.g., the user is not inproximity with user system 102, and accesses user system 102 via network100 and a separate user system). A user accessing user system 102 canaccess content stored by content management system 104. In variousembodiments, content management system 104 comprises one or moredocument repository systems, content server systems, docbroker systems,or any other appropriate systems. In some embodiments, the internaloperation of content management system 104 is transparent to a useraccessing the system via user system 102 (e.g., the user is unaware ofthe configuration of repository systems, content servers, etc., formingcontent management system 104). In some embodiments, content managementsystem 104 comprises a system for automatic elevation of systemsecurity.

FIG. 2 is a block diagram illustrating an embodiment of an enterprisecontent management system and associated clients. In the example shown,client 200, client 202, and client 204 comprise user systems (e.g., usersystem 102 of FIG. 1). In some embodiments, each of client 200, client202, and client 204 comprises interface API software for accessing adocbroker and a content server. A client stores a network address of anearby docbroker (e.g., docbroker 206 or docbroker 208) and queries thedocbroker in order to determine the network address of a content server(e.g., content server 210 or content server 212). In variousembodiments, the docbroker informs the client of the nearest contentserver, of all content servers within a given distance, of all contentservers that have access to a requested segment of data, or of any otherappropriate content server. Upon receiving one or more networkaddresses, the client contacts a desired content server using itsinterface API. The interface API allows the client to make data requeststo the content server that can be properly understood by the contentserver. The content server interprets the request and, if necessary,retrieves the data from database 214. In various embodiments, allcontent servers access data from a single database (e.g., database 214),there are multiple databases, there is one database for each contentserver, there are multiple databases for one or more content server, orthere are any appropriate number of databases. In various embodiments,database data is stored in a directory structure mounted on the contentserver, in a relational database management system, on acontent-addressed storage device, on an external storage area, or in anyother logical way. In some embodiments, when a content server receives acommand to initiate automatic elevation of system security (e.g., from asystem administrator) the content server automatically performsconfiguration steps to create certificate-authenticated communicationsbetween the content server and other associated content servers,docbrokers, and client systems. In some embodiments, the content serverdistributes certificates or collections of certificates (e.g., truststores or key stores) to associated systems to enable elevation ofsystem security.

In some embodiments, the Docbroker is like a nameserver. When a clientwants to find out available servers for a docbase, it looks up theservers in Docbroker's ServerMap. Once the clients get details of theserver, then they directly connect to the server for rest of their otheroperations. This is similar to a DNS lookup. In some embodiments,Content Servers do not directly talk to one other on the network. IfContent Server 1, for instance, has to do configuration changes toContent Server 2, it goes to the database directly, looks up ContentServer 2's configuration object and updates it. This will be picked upContent Server 2 in a configured amount of time (called change checkerinterval) and on detecting the update, Content Server 2 willreinitialize itself using the new configuration.

FIG. 3 is a block diagram illustrating an embodiment of a trust store.In some embodiments, a trust store is created and distributed by acontent server as part of a process to enable elevation of systemsecurity. In the example shown, trust store 300 comprises certificate302, certificate 304, and certificate 306. In various embodiments, truststore 300 comprises, 1, 3, 12, 34, 178, or any other appropriate numberof certificates. In some embodiments, certificate 302, certificate 304,and certificate 306 each comprise an authentication certificate forauthenticating communication between a content server and a docbroker.In some embodiments, the trust store is distributed to content serversas part of a process to enable elevation of system security. In someembodiments, the trust store or truststore comprises a cabinet/filecontaining a collection of certificates, where there is no passwordrequired for this file. In some embodiments, PKCS#7 (e.g., public-keycryptography standard #7) is used for the format for the trust store.

FIG. 4 is a block diagram illustrating an embodiment of a key store. Insome embodiments, a key store is created and distributed by a contentserver as part of a process to enable elevation of system security. Inthe example shown, key store 400 comprises certificate 402, certificate404, and certificate 406. In various embodiments, key store 400comprises 1, 4, 22, 144, 783, or any other appropriate number ofcertificates. In some embodiments, certificate 402, certificate 404, andcertificate 406 each comprise an authentication certificate forauthenticating communication between two content servers. Key store 400additionally comprises security key 408. Key store 400 comprises anencrypted collection of certificates, with security key 408 the requiredsecurity key to decrypt the key store. In some embodiments, the keystore is distributed to content servers, docbrokers, and client APIs aspart of a process to enable elevation of system security. In someembodiments, the key store or key store comprises a cabinet/filecontaining a collection of certificates along with a private key, wherethere is a password required for this file to prevent unauthorizedaccess to the private key. In some embodiments, PKCS#12 (e.g.,public-key cryptography standard #12) & JKS (e.g., java key store) isused for the format for the key store.

In some embodiments, there are many advantages using PKCS#7 and PKCS#12formats: 1. They are the standard widely used formats; 2. When customerrequest for Certificates, these are formats that most CertificateAuthorities issue them; 3. PKCS#12 has its own password and hence issecure; 4. These formats are platform independent; 5. These are inbinary format and hence cannot be easily tampered with w/o causingcorruption; 6. Can be used by C++ and other native libraries includingJava libraries. Java key store has most of these benefits, except thatit is restricted to Java code and C++ natively cannot use them.

In some embodiments, a key store can act as a trust store.

In some embodiments, a content server has configuration settings in a<server>.ini file:

Keystore_file=<store containing server certificate & private key>

Keystore_pwd_file=<path to file having encrypted keystore password>

Truststore_file=<store having trusted docbroker certificates>

In some embodiments, a docbroker has configuration settings in a<docbroker>.ini file:

Keystore_file=<keystore containing docbroker certificate & private key>

Keystore_pwd_file=<path to file having encrypted keystore password>

In some embodiments, a client DFC has configuration settings:

-   -   dfc.security.ssl.truststore—path to the truststore containing        certificates for server and docbroker    -   dfc.security.ssl.trust_storepassword—password of the truststore,        should be encrypted    -   dfc.security.ssl.use_existing_truststore—should use the existing        keystore or not

In some embodiments, options for certificate creation include: expirydate (e.g., 1 year), key algorithm (e.g., RSA, sometimes fixed), keylength (e.g., 2048), organizational unit (e.g., DCTM), organization(e.g., a company name), a state (e.g., CA), a province (e.g., PLE), acommon name (e.g., broker/CS name, sometimes derived from system), andemail address (e.g., support@emc.com).

FIG. 5 is a flow diagram illustrating an embodiment of a process forautomatic elevation of system security. In some embodiments, the processof FIG. 5 is executed by a content server (e.g., content server 210 ofFIG. 2). In the example shown, in 500, the server determines that anindication to set a secure mode comprises an indication to set acertificate mode (e.g., a mode where secure communications areauthenticated using certificates). In some embodiments, the indicationto set a secure mode comprises an indication sent to the server by asystem administrator (e.g., the system administrator indicates to theserver to set a certificate mode). In 502, one or more connected systemsare detected. In various embodiments, one or more connected systemscomprise other content servers, docbrokers, client systems, databases,or any other appropriate systems. In 504, one or more certificates areselected. In some embodiments, selecting certificates comprisesselecting certificates that exist on the content server (e.g.,previously generated certificates or certificates received fromconnected systems). In some embodiments, selecting certificatescomprises generating new certificates. In some embodiments, onecertificate is selected corresponding to each connected system detectedin 502. In some embodiments, selecting one or more certificatesadditionally comprises packaging certificates into a trust store. Insome embodiments, selecting one or more certificates additionallycomprises packaging certificates into a key store. In 506,initialization files are updated. In various embodiments, initializationfiles are updated on content servers, on docbrokers, on client systems,or on any other appropriate systems. In 508, local and connected systemsare reinitialized.

FIG. 6 is a flow diagram illustrating an embodiment of a process fordetecting one or more connected systems. In some embodiments, theprocess of FIG. 6 implements 502 of FIG. 5. In the example shown, in600, all content servers stored in the docbase are determined. In someembodiments, the docbase comprises a database stored on a content serverof other content servers the content server is in communication with. In602, all docbrokers stored in the server configuration file aredetermined. In some embodiments, the server configuration file comprisesa server initialization file. In some embodiments, docbrokers the serveris projecting to are also determined.

FIG. 7 is a flow diagram illustrating an embodiment of a process forselecting one or more certificates. In some embodiments, the process ofFIG. 7 implements 504 of FIG. 5. In the example shown, in 700, the nextconnected system (e.g., the next connected system of the connectedsystems determined in 502) is selected. In some embodiments, the nextconnected system comprises the first connected system. In 702, it isdetermined whether a certificate for the system has been received. Insome embodiments, it is determined whether a certificate for the systemhas been created previously (e.g., whether a certificate for the systemis already present). In the event a certificate for the system has beenreceived, control passes to 706. In the event a certificate for thesystem has not been received, control passes to 704. In 704, acertificate for the system is created. For example, a certificate isgenerated with a key with a specific length. In 706, it is determinedwhether there are more connected systems. In the event there are moreconnected systems, control passes to 700. In the event there are notmore connected systems, control passes to 708. In 708, a trust store(e.g., a trust store as shown in FIG. 3) is created with all docbrokercertificates (e.g., certificates corresponding to docbrokers). In 710, akey store (e.g., a key store as shown in FIG. 4) is created with alldocbroker certificates and all content server certificates (e.g.,certificates corresponding to content servers).

FIG. 8 is a flow diagram illustrating an embodiment of a process forupdating initialization files. In some embodiments, the process of FIG.8 implements 506 of FIG. 5. In the example shown, in 800, docbrokerinitialization files are updated to indicate a key store file (e.g., thekey store file created in 710 of FIG. 7) and associated password. In802, content server initialization files are updated to indicate the keystore file and associated password and a trust store file (e.g., thetrust store file created in 708 of FIG. 7). In 804, client APIinitialization files are updated to indicate the key store file andassociated password.

FIG. 9 is a flow diagram illustrating an embodiment of a process forreinitializing local and connected systems. In some embodiments, theprocess of FIG. 9 implements 508 of FIG. 5. In the example shown, in900, a reinitialization request is sent to docbrokers (e.g., docbrokersidentified in 602 of FIG. 6). For example, the reinitialization requestindicates to reinitialize the communication with other systems using thecertificates as stored on the system. In 902, a reinitialization requestis sent to client API sessions (e.g., to any clients communicating withthe content server). In 904, a reinitialization request is sent tocontent servers (e.g., content servers identified in 600 of FIG. 6). Forexample, the reinitialization request indicates to reinitialize thecommunication with other systems using the certificates as stored on thesystem. In 906, local network connections (e.g., network connections ofthe content server) are reinitialized.

FIG. 10 is a flow diagram illustrating an embodiment of a process forautomatic setting of security level. In the example shown, in 1000 anindication is received from a user. For example, an administrator setssecurity level using a SET_SECURITY_LEVEL command. In 1002, it isdetermined whether the certificate security mode is set. In the eventthat the certificate security mode is set, in 1004 it is indicated toset certificate security mode. In the certificate security mode, thesystem will automatically start using certificates when communicatingbetween components of the system. In the event that the certificatesecurity mode is not set, in 1006 it is indicated to set anonymoussecurity mode. In the anonymous security mode, the system willautomatically start using anonymous secure sockets layer (SSL) whencommunicating between components of the system.

FIG. 11 is a flow diagram illustrating an embodiment of a process forautomatic setting of security level. In the example shown, in 1100 anindication is received to set certificate security mode. In 1102 it isdetermined whether a certificate is provided. In the event that acertificate is provided, control passes to 1112. For example, anindication of a certificate can be provided by specifying DOCBROKER,<docbroker Name>, certificatefile name, certificate password file;SERVER, <server_config name>, certificate file name, certificatepassword file, truststore file name; and/or DFC, <path todfc.preperties>, dey store path name, key store password. In the eventthat a certificate is not provided, in 1104, docbroker certificates aregenerated. For example, a certificate is created for each of thedocbrokers configured in the server.ini and to which the server isprojecting to. In 1106, content server certificates are generated. Forexample, a certificate for the content server itself is created and foreach of the other server config objects stored in the docbase. In 1108,content server truststore is generated. For example, a truststore iscreated which will have all the docbroker certificates. In 1110, a DFCtruststore is generated. For example, a DFC keystore is created whichwill have all the docbroker certificates and all server_configcertificates. In 1112, docbroker ini files are updated. For example, thedocbroker.ini files are updated for each of the docbrokers to set thedetails regarding the certificate file (e.g., a P12 file) and thepassword file (e.g., a P12 password file). In 1114, server ini files areupdated. For example, the server<server>.ini files are updated for eachof the server_config to set the details regarding the certificate file(e.g., a P12 file) and the password file (e.g., a P12 password file) andthe docbroker trust file. In 1116, DFC properties files are updated. Forexample, the dfc.properties file is updated to point to the dfc.keystoreand password. In 1118, docbrokers are reinitialized. For example, adocbroker is sent to do a reinit. This is similar to a checkpointrequest. Upon receiving this, the docbroker will do a netwise connectionremit with the parameters set in the docbroker.ini. In 1120 DFCs arereinitialized. For example, a DFC request is sent to all connected DFCsessions. This is an out-of-band data which the DFC client gets and doesa network reinit. In 1122, servers are reinitialized. For example, thedocbase property is modified to indicate to other server server_config'sto do a reinit. This is similar to how a dormancy state is broadcast.The local server is reinitialized for its network connections. Thisreads the configuration from the updated server-,server_config>.ini. In1124, a report is generated. For example, the report includes adescription of the prior configuration listing security levels andconfigurations, results of the update operation, and resultingconfiguration once the reinit is complete.

FIG. 12 is a flow diagram illustrating an embodiment of a process forautomatic setting of security level. In some embodiments, the system(e.g., the content server) does the opposite of the process in FIG. 11where it comments out the settings referring to certificates and itssettings. In the example shown, in 1200 an indication is received to setanonymous security mode. In 1202, docbroker ini files are updated. Forexample, the docbroker.ini files are updated for each of the docbrokersto set the details regarding not using the certificate file (e.g., a P12file) and the password file (e.g., a P12 password file). In 1204, serverini files are updated. For example, the server<server>.ini files areupdated for each of the server_config to set the details regarding notusing the certificate file (e.g., a P12 file) and the password file(e.g., a P12 password file) and the docbroker trust file. In 1206, DFCproperties files are updated. For example, the dfc.properties file isupdated to not point to the dfc.keystore and password. In 1208,docbrokers are reinitialized. For example, a docbroker is sent to do areinit. This is similar to a checkpoint request. Upon receiving this,the docbroker will do a netwise connection reinit with the parametersset in the docbroker.ini. In 1210 DFCs are reinitialized. For example, aDFC request is sent to all connected DFC sessions. This is anout-of-band data which the DFC client gets and does a network reinit. In1212, servers are reinitialized. For example, the docbase property ismodified to indicate to other server server_config's to do a reinit.This is similar to how a dormancy state is broadcast. The local serveris reinitialized for its network connections. This reads theconfiguration from the updated server-,server_config>.ini. In 1214, areport is generated. For example, the report includes a description ofthe prior configuration listing security levels and configurations,results of the update operation, and resulting configuration once thereinit is complete.
